As a competition shooter, instructor and occasional hunter, who requires perscription RX lens when not wearing contacts, I've owned lots of different brands: Decots, Rangers, NYX, Sun Busters, Serengetti to name a few.
Recently invested in HiDefSpex Sebrings because the frame style accepts RX lenes. I have some brands with RX inserts, but since the Sebring frames take an RX lenses I just went for it. I was reticent to spend the money (and it is an investment!) on what appear to be the world's most expensive shooting glasses. But glad I did. Frames are adjustable for fit. Lenses are ballistic quality material that doesn't seem to have distortion and are highly rated for safety. Instead of fooling around with mulitple tints HiDef's use a unique approach based on just amount of light transmission (LTM 20%; 40%; 65% 99%) from one tint color to cover all shooting conditions. If you're serious about seeing the target (clay or with feathers) I recommend them.
